September 11 did not hurt the United States one little bit. It was infinitesimal amount of damage to a gigantic country, and only a security narcissist would suggest that the US change it's posture as a result.

When you were in school and a bully hit you, did you go whining to the teacher? Crying how bad it hurt? We Americans must NEVER EVER whine about being damaged, it only emboldens those who hate us.

Houses have much larger square footage, which seems preposterous, because you don't need it, but that's the economics of home-building. Furthermore, jobs are shorter-term, meaning people have to be mobile. The bonanza of home-building after World War II seems to really have been a one-off. I believe in world trade, but it has killed this lifestyle.

Much truth in what you say, but the US is urbanizing and there is substantial demand for mass transit between urban cores. It seems to be met now mostly by bus, where the prices can be unbelievably low, and you can also work with wifi. That is the future, because car ownership have become a never-ending payhole.
